As a result, this addiction can produces seriously problems to our psychologist and physical efficiency of human body.

The computers fans stop to practice any exercise, they not even go to the kitchen to get ready something of eating because that removes them time in front of the screen; their muscles begin to suffer nuisances, like the “tunnel of carpio” on hand created by the use of the mouse. Therefore, we have to realize that there are more forms to amusing our time and that, if is too necessary the use of computer, we can take some hours to relax our muscles and improve other kind of activities.
